I have told him already he has just the proper temperament to stand the drug. Such people are rare: HE is one of them." We administered the dose, trembling. Sebastian took it like a man, and dropped off instantly, for lethodyne is at least as instantaneous in its operation as nitrous oxide. He lay long asleep. Hilda and I watched him.
Their flanks were blotched with a livid nitrous efflorescence, with flaring sulphur, unhealthy verdure of pitchstone, streaks of arsenical vermilion; their beds a frantic maze of boulders. He beheld this crazy stratification, this chaos of incandescent nature, sent in a flame of deep blue sky and sea.
The young lady's feats, in particular, produced great merriment, and so intimidated the ladies, that not one, after this time, could be prevailed upon to look at the green bag, or hear of nitrous oxide, without horror! But more perilous experiments must now be noticed. Mr. Davy having succeeded so well with the Nitrous Oxide, determined even to hazard a trial with the deadly Nitrous Gas.
Thus, air contained in a vessel in which a lighted candle had gone out, or a living animal had breathed until it could breathe no longer, was called "phlogisticated." The same result was supposed to be brought about by the addition of what Priestley called "nitrous gas" to common air.
Lavoisier thought of these reactions as the tearing asunder, by mercury, of nitric acid into definite quantities of its three components, themselves distinct substances, nitrous air, water, and oxygen; and the combination of the mercury with a certain measurable quantity of one of these components, namely, oxygen, followed by the union of this compound of mercury and oxygen with what remained of the components of nitric acid.
When the most powerful alleviative known to medical science has bestowed the last Judas kiss which is necessary to emasculate its victim, and, sure of the prey, substitutes stabbing for blandishment, what alleviative, stronger than the strongest, shall soothe such doom? I may give chloroform. I always do in the denouement of bad cases ether nitrous oxyd.
And not only if you look upon a Glass half full of Aqua-fortis, or Spirit of Nitre, and half full of Nitrous steams proceeding from it, you will see the Upper part of the Glass of the Colour freshly mention'd, if through it you look upon the Light.
The conclusions regarding the composition of nitric acid drawn by Lavoisier from these experiments was, that "nitric acid is nothing else than nitrous air, combined with almost its own volume of the purest part of atmospheric air, and a considerable quantity of water."
I am not sure that it was correct, for the effects of nitrous oxide is, perhaps, due to a deprivation of mechanically mixed air.
"You find it taste somewhat like vinegar?" asked Uncle Richard. "Indeed I do," answered Mr Laffan. "Is it always like this?" "Yes," said Uncle Richard; "it comes in its present state out of the mountain, and you were not far from the truth in your description, as when analysed it is found to be acidulated, nitrous, and ferruginous.
